crystal structure of the title compound has been determined by single-crystal X-ray diffraction. It crystallizes in the monoclinic space group C2/c with a=12.531(1), b=3.8960(2), c = 28.733(2) Å, b = 100:760(1)°, Z = 4. Through intermolecular weak C-H· · ·O hydrogen bonding and p-p stacking interactions, a supramolecular 3D structure is formed. Graphical Abstract Synthesis, Crystal Structure and Fluorescence
报道了一种使用有机氨氧基自由基的一锅反应作为催化剂合成 2,6-二取代苯并双恶唑的有效且清洁的新好氧方法。2,6-二(噻吩-2-基)-苯并[1,2-d : 4,5-d']双恶唑在自由基4-甲氧基-TEMPO的催化下合成,并通过1H和13C NMR光谱表征、HRMS,以及元素分析、UV/Vis 和发射光谱。标题化合物的晶体结构已通过单晶 X 射线衍射确定。它在单斜空间群 C2/c 中结晶,a=12.531(1), b=3.8960(2), c = 28.733(2) Å, b = 100:760(1)°, Z = 4。通过分子间弱CH···O氢键和pp堆积相互作用,形成超分子3D结构。图形摘要综合,
